Abstract

A situation display system has a movable section for attachment to a helmet nd a stationary section, including a stationary map providing a real map background for showing situation display elements on the map. The movable section is connected through a flexible cable to a device for the remote control of the situation display elements which are computer generated. By accurate measurements of the location of the helmet and its distance to the map, signals are provided which are processed independently of any movements of an operator wearing the helmet so that the elements are correctly displayed and seen on the map. Thus, a tactical situation display is obtained for a military command system.
